Construction kit made of concrete paving stones

ABSTRACT

The invention relates to a construction kit made of concrete paving stones comprising substantially prismatic stone bodies of a uniform height and upright lateral surfaces. A plurality of stone paving stones ( 2 ) arranged in rows and having the same width in addition to the same or different lengths can be placed manually or placed by means of a machine with continuous or offset joints in said joint areas. A plurality of rows of paving stones that are arranged next to each other in a parallel position is used to form a rectangular or square packet that can be placed using a machine. The paving stones ( 2 ) have side surfaces ( 4 ) which have head pieces ( 2′ ) that are defined by a wavy line along part of their height and base pieces ( 2″ ) in sections, comprising domed areas ( 5 ) or projections jutting out laterally in relation to the head pieces ( 2′ ) extending along another part of their height. When the packets are assembled for placement in the vicinity of the end stones that make up a row of paving stones, they form a line of continuous joints or provide substantially winding-shaped joints ( 7 ) if so desired by replacing different sized end stones from adjacent packets that have been moved towards each other.

[0001] The invention relates to a construction kit with paving stones made of concrete material, with substantially prismatic stone bodies having the same height and upright side surfaces.

[0002] It is known that when paving stones that are assembled in laying packets are laid by means of machines, through-extending joints form in the laid composite of stones in the joint areas of the placed packets. Such joints have an unfavorable effect on the visual appearance of the placed composite of stones.

[0003] The problem of the invention is to provide a construction kit of the type specified above which can be assembled with other construction kits to form laid composites with the help of machines, and which permits forming simple continuous or offset joints selectively between adjacent construction kits.

[0004] Said problem is solved according to the invention by a number of paving stones having the same width and the same or different lengths, such paving stones being arranged in rows and having a number of rows of paving stones arranged next to each other for forming a rectangular or square packet that can be laid using a machine. The stone bodies have side surfaces which have head pieces, in particular head pieces defined by a wavy line along part of their height, and base pieces in sections, comprising domed areas or projections jutting out laterally and transversely beyond the head pieces, said base pieces extending along another part of their height, whereby the laying packets permit within the placed composite within the region of the end stones of the rows of paving stones the formation of either a line of continuous joints, or the formation of substantially meander-like joints by replacing end stones with different lengths from adjacent laying packets that have been moved toward each other. The laying packets as such can be shaped in single pieces due to their prismatic form, and they can be safely picked by machines and laid as a prismatic packet, whereby in the laid condition, it is possible to selectively form lines of continuous, through-extending joints, whereas joints offset in the form of a meander can be formed by replacing row end stones with different lengths of adjacent laying packets, such meander-like joints resulting in a laid composite which is closed within itself and visually coherent without showing the individual construction kits.

[0005] In an advantageous embodiment of the construction kit, provision is made that the head and/or base pieces of the paving stones are provided with broken or rounded corners and/or edges in order to exclude or minimize the risk of breakage in said regions, and to assure that walking on the laid composite is possible without any obstructions.

[0006] It was found that it is advantageous, furthermore, if the top surfaces defining the limitation of the head pieces, which are the treads of the paving stones, are arched outwardly in a curved way. In this way, the paving stones impart the appearance of natural stones, and the laid composite has the visual appearance of some type of natural stone paving. The curves of paving stones with large surface areas, viewed from the top, are usefully kept flatter, and the curves of paving stones having a small surface area viewed from the top, are usefully provided with a more pronounced curvature.

[0007] Finally, provision is made that the outward dome-like projection or attachments arranged on the base pieces of the stone bodies are arranged on the side surfaces of the base pieces with spacings between each other, and that the dome-like projections or attachments form support elements for adjacent stone bodies, whereas the outward dome-like projections or attachments jointly with outward dome-lie projections or attachments of adjacent stone bodies create intermediate spaces in the joint areas that serve as water passage openings. The sizes of the cross sections of the water passage openings are substantially determined in this connection by the length and width of the domed areas or attachments, as well as by their spacings from each other, and by their number.

[0027] The construction kit 1 shown in FIG. 1 is formed by a number of paving stones 2 made of concrete material. FIGS. 2 and 3 show that the paving stones 2 are designed with a prismatic shape. Said paving stones have a head piece 2′ with a waveline-shaped circumferential surface 3, and a base piece 2″, which is provided in the circumferential surface 4 with a number of dome-like projections 5 or attachments. The dome-like projections 5 are formed on the base piece 2″ over parts of the length of the circumferential surface with a spacing from each other. The paving stones 2 are arranged in rows for forming the construction kit 1, as shown in FIG. 1 and FIGS. 7 and 8, whereby the paving stones 2 of each row are designed with the same width, but with identical or different widths. The lengths of the rows of paving stones of each construction kit 1 are overall designed according to a pattern which, in the exemplified embodiment according to FIGS. 7 and 8, is selected to measure, for example 1200 mm×760 mm. It is understood that the raster measure of the construction kits can be selected in any other desired size. The construction kits 1 so formed as laying packets can be safely seized and laid with the help of machines.

[0028]FIGS. 7 and 8 show the bottom views of the paving stones 2 referred to as the core concrete sides, which are assembled in rows of any desired length, but with identical widths to form a laying packet. The numerals 12 connected by the hyphens 11 represent measurement data in millimeters. In FIG. 7, the paving stones all having the same low width but different lengths are assembled to form a construction kit, and in FIG. 8 the paving stones all having the same large width and different lengths are assembled to form a construction kit.

[0029] The dome-like projections 5 on the circumferential surfaces 4 of the base pieces 2″ serve in the construction kit 1, the latter being assembled to form a laying packet, for mutually supporting adjacent paving stones 2, or rows of paving stones. By dimensioning the dome-like projections 5 accordingly, the latter permit the formation of passage openings 6 (FIG. 18) for water within the zones of the joints 7, via which water can drain off into the underground.

[0030] In FIG. 9, the construction kits 1 conforming to the pattern in FIG. 7 are combined with construction kits 1 according to FIG. 8 to form a laying composite, whereby the construction kits 1 in the laid composite show lines of continuous joints 7 in the transverse and longitudinal zones of adjacent construction kits 1. In FIG. 10, a modified laying composite is formed by combining construction kits of FIGS. 7 and 8. In connection with said laying composite too, provision is made for through-extending joints in the transverse and longitudinal regions of adjacent construction kits. The construction kits 1 of the center zone of the laying composite in FIG. 10 correspond with the construction kit 1 of FIG. 7, and the two lateral sections of the laying composite correspond with the construction kits 1 of FIG. 8.

[0031]FIGS. 11 and 12 represent a laying composite formed by the construction kits 1 of FIG. 7. In this connection, the construction kits 1 each are picked up by means of a machine in the form of a rectangular laying composite and then laid, and the laying pattern according to FIG. 11 is then obtained by subsequently replacing the row end stones 2 (shown by dashed lines in FIG. 12). Instead of the through-extending continuous joints 7, meander-shaped joints 7 are obtainable within the rows of the paving stones by replacing the dashed row end stones. A laying pattern that is continuously closed is obtained in this way.

[0032] The same considerations apply to the laying patterns of FIGS. 13 and 14. In the present laid composite, construction kits according to FIG. 8 are employed, whereby a laying pattern of FIG. 14, with meander-like joints 7, is again obtainable by exchanging paving stones at the ends of the rows of adjacent construction kits 1 (shown in the exemplified embodiment by dashed lines), said laying pattern of FIG. 14 being closed within itself. It is not possible for the viewer to recognize that the laid composite is created with a number of construction kits laid by a machine.

[0033] In the exemplified embodiment according to FIGS. 15 and 16, constructions kits of FIG. 7 and FIG. 8 are employed next to each other. The joints 7 are provided with a meander-like shape by replacing end stones of the rows (shown dashed in FIG. 16).

[0034] Deviating from the above, FIGS. 4 and 5 show a paving stone 2 for a construction kit 1 which, instead of the head pieces 21 defined by a wavy line, has the head pieces 2′ with the rectangular shape, whereas the base pieces 2″, in the laid condition, have the attachments 5 for creating water passage openings 6 in the circumferential surfaces 4.

[0035] It was found to be advantageous if the paving stones 2 have the outwardly extending dome-like projections within the zone of their top sides 2′″, as it is shown particularly in FIGS. 4 and 5. Said dome-like projections 13 have a radius of about 1443 mm. Provision is made in this connection that viewed from the top, paving stones 2 with large surface areas have the relatively flat dome-like projections 13, whereas the paving stones 2 with small cross section sizes have the dome-like projections 13 with a strong curvature.

[0036]FIG. 6 shows another paving stone 2 by a top view. Said paving stone is provided with the side surfaces 14 with parallel faces, said surfaces supporting rib-like attachments 5 that are spaced from each other. Said attachments 5 serve as spacer means versus adjacent paving stones and for forming water passage openings within the areas of the joints. In the present embodiment, too, the top side of the paving stone 2 has an outwardly pointing dome-like projection 13.

[0037]FIG. 17 shows a laying pattern in connection with which a laying pattern that is closed within itself can be obtained without requiring any replacement of end stones of the rows by associating the construction kits 1 with each other in a suitable way.
